A Koala bear decides he wants to get laid, so he picks up a hooker. He goes down on her several times and they are really enjoying themselves. After they are finished the koala bear starts getting dressed.
The hooker says, "wheres my money?"

The koala bear shrugs his shoulders. The hooker repeats herself asking for her money. Again he shrugs his shoulders. The hooker grabs a dictionary and looks up the word hooker and shows it to the koala bear.
It says "gets paid for sex."
